This story is really good. You have made a very interesting world for your characters and I am excited to read more as you update it. One thing I would mention though is that the Robin in teen titans is actually Dick Grayson not Tim Drake, Just wanted to point that out.

To rushed. Waaay to rushed. Decent idea with a cool start. Explained enough to keep it interesting without boring the reader but suddenly once he reaches Titan-verse he just falls in love and vice versa out of nowhere. No build up, no explanation, just "Here's my blood, summon me".

Dude awesome story. Very well written and I love how you give us readers glimpses of Naruto's past as a hellhound. Please continue to write this story and any others you've written and or going to write. Can't wait for the next chapter.

The second to last was the face of a beautiful woman, with sharp canines and a bleeding tongue. A dhamphir had apparently been the closest to the last head born as she was eyeing him like a side of meat...What? Explain this please.
